Shannon and Jane have $221. Wendy and Shannon have $273. The ratio of Jane to Wendy is 1 : 5. How much does Shannon have?
Amount that Jane has = 1 u
Amount that Wendy has = 5 u
The amount that Shannon has is the repeated identity.
Shannon + 1 u = 221 --- (1)
Shannon + 5 u = 273 --- (2)
(2) - (1)
5 u - 1 u = 273 - 221
4 u = 52
1 u = 52 ÷ 4 = 13
From (1):
Shannon + 1 u = 221
Shannon + 1 x 13 = 221
Shannon + 13 = 221
Amount that Shannon has
= 221 - 13
= $208
Answer(s): $208
